:lmao:

I don't think there is any concern about DBA levels here

175 miles east of Los Angeles. However not much space for auto cross but could be another option for a California stop

And even some days the track officials have been known to move around with hand held sound meters. True story.

Big picture - They're bureaucrats driven by environmentalist groups using "our" tax dollars attempting to shut down down race tracks and other "undesirable" activities by implementing unrealistic regulations.

One of the better offenses I've seen is this group: http://www.sharetrails.org/

They managed to gather mass and revenue by uniting motorcyclists, atv'ers, snowmobilers, mountain bikers, and equestrians to fight recreational land closures. They've made a difference.

I am going to guess
 

that my car will not qualify to run, which is fine. My question is can I still run/participate and not get scored?

For me it is about hanging with my peeps and getting to drive some awesome tracks.

Looks like I might have just bought myself some time as Laguna
is not going to be an option at 90db.. I will talk to my Muffler guy who
is the man for Norcal Shelby group.... he told me a while back that some
of the Trans Am cars were running two sets of mufflers to get down to 105

My Pantera with the short exhaust will be an issue unless I split the
180's exiting point which is not an option now that I welded those holes
up... The firebird might have a chance but not sure it is worth the effort
in order to run the one event.. have to retune it etc

I did run Laguna the first time this year (105 day) and yes it is a world class
track but to tell the truth I like thunderhill a lot more and with the
new track extension it is going to be awesome.. I did have to build
some new mufflers for Thunderhill a year or two back but a least it is 98 db

I love the out of state tracks- Reno, Pahrump and Firebird... I can run
the 4" straight exhaust on the car and make it seem like I am really
running on a track the way they used to run

My Vintage Can Am buddy stated they were looking at putting mufflers
on them a few years back but I have not heard anything else recently

The thing that hurts these racetracks is housing close to the track. Even airports have noise restrictions over certain neighborhood. Have you ever flown out of John Wayne in Orange County?

I wouldn't buy a house next to an airport or racetrack cause I know its undesirable for resale. The tracks or airports were there way before the homes. There should be a clause on the title of these homes that there is noise due to proximity to certain venue. Then they can't complain about it.

Portland International Raceway should be the model for all race tracks. Its got a golf course on one side, swamp land and expo center on the other side. Its got a I5 running thru the front of it. No one to complain about noise. Oh and if you want to complain about noise, the city of Portland owns it good luck with that complaint. Its normal track days is 105db and 4 times a year they bump it up to 115db.

I don't think Oregon Raceway Park has a db restriction, at least I've never heard mention. :unibrow:

Hopefully Laguna Seca doesn't fall victim to housing immigrants as so many race tracks around the country have.

It looks like 92 dB for that weekend 8-9 March according to the Laguna Seca calender. It is a lot better than a 90 dB, but it will still be a concern. Hopefully USCA will post this actual information on the website so any going know what to prepare for.

Yeah but ORP is in the middle of no where. Who would live out there? PIR is 5 minutes to downtown Portland.
I can't figure out why Laguna has a sound restriction, I just google mapped both tracks and housing seems to be just as close. Only difference I see is that in Portland people are probably more annoyed with the train track noise and horn blowing than the track.

The big difference is one is in California....everything is regulated to death here...

I think often when they measure DB it is not Equal, since they measure every type of engine on the same RPM.

An 7 liter v8 makes a lot of "noise" on 3500rpm but an 2.5 litre is quiet until 7000plus... On-track measuring could be different though, but they often seem to want to find a way to get you if they dont right away..

It is a bit ironic that you can have a street car that is not allowed as an race car, because of noise..


It seems this is a worldwide problem.

Many years ago, theres was a series here who had this problem, mounting the exhaust upwards in the end helped some, so the exhaust did not "hit" the ground.

Crosses and stuff in the end of exhaust and such helps too, on a street car you could make some that is mountable of some sort. If you are on the edge it can work, go to Radio shack and buy a cheap db tester to test at home?

I have seen some pretty desperate sound "muffle" systems some times, that is made on-site.. He..He..

TRUTH!!!

Laguna Seca is a park owned by Monterey County. It is not your typical track trying to make money. The hillsides around the track have houses and sound travels differently. Thunderhill when the expansion is done is supposed to be the longest track in North America. Can't wait.

Never heard about that. That's cool. I doubt my memory will be good enough to to memorize and get comfortable on something that long. I know Spring Mountain, with the addition of their new track sections, is configurable up to 6.75ish" miles.

Start memorizing boys! http://thunderhill.com/images/librar...hill-west1.jpg

Geesh! I'd have to take my tom tom with me to get around that place! Might want a bigger fuel cell also. Lol.

Thunderhill new track
 

Not to worry --- The track will mostly be run as TWO separate tracks -- very few events will get the entire track to run on. NorCal Shelby has a "whole track" event coming up... so that will be a hoot!!!

Things are regulated to death in California but Laguna Seca is the only track that has the ridiculously low db limits. Sonoma Raceway is a fantastic road course to drive on with decent facilities and I believe they did lower their db level down to 103 from 104. Thunderhill is another great place to run and they may have lowered their db levels from 104 to 103 also. Buttonwillow is another great track and perfect for the beginner. At least 15 different configurations, no elevation changes, and run off for days.
So don't blame California.....HA :lol:

California sucks. I never can figure out why I spend so much time there.... HAHAHAHAHAHAHAHA


Maybe it's because there's so much to do!!

You do spend a lot of time here and I thought for sure you would be buying in The Napa Valley. I'm thinking the only reason your wife chose Sun Valley is because she chose a state that could get you as far away from Charlie as possible but she could still enjoy. :lol:

She pretty much hates him.... So do I.

Thanks for the character reference. I'll be sure to keep an eye out. :lol: :lol: :lol:

I'm feeling the love.....

I've met Charlie and he's a really nice guy. I can't figure out why you guys are baggin on him.:headscratch:

You probably met him 15 minutes after he bought his 1300th car from Stielow ... and he was in a good mood.

I'm going to try and make the event in PA. I can get some driving in, and learn a lot from watching and talking.

I have no high hopes of winning, but it will be fun. and you get to see a lot of really cool cars.:idea:
